Recent Questions Javascript Tree Collapsing Expanding
Q: As a part-time webdeveloper I have gotten very interested in your product. I really appreciate a number of things
- it's very flexible
- it's very easy to work with
- examples nicely show the capabilities
But I have a couple of questions:
- When opening a menu, there is an option for keeping the menu-item that has been pressed hightlighed (so that the user can see what he/she pressed). Is it possible, programmatically, to decide when this highlighting should be removed? The scenario is that, when a menu-item is clicked the used might browse for a couple of pages within the context defined by the menu-item, but when the user leaves, the menu-item should no longer be highlighted. I will (programmatically) decide the context, but is it possible for me to interact with the menu, and for example decide explicitly which menu should be highlighted?
- Our design department would like the menu containing the elements: "Skovdrift, Juletreer, Skovrejsning, etc". Please notice that "Brende" is supposed to show a menu item that is hightlighted. Is is possible to create this menu such that it is dynamic and each item is text-based (and not based on two pictures for each menu-entry: hightlighted and not)? I've been wondering how to solve this problem, but I cannot figure out a solution. The problem that I is stuck at, is how organise this speciel "frame" around each menu-element. Something that be partly accomplished using "arrowImageMain", but that does not bring me all the way. Please notice that the menu-items might not have any sub-menu.
A: I suppose that you're saying about
var pressedItem=-2;
Defines an item that will appear in the highlighted state
(-2 - normal mode, -1 - toggle mode is active, but highlighted item not defined, 0,1,2,3,... - # of pressed item including separators)
This parameter will not approach you.
You should set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
Q: We are looking for how we have to do for the previously clicked item in the dynamic tree menu
remains highlighted to inform user what is his current page.
It is possible to achieve this behavior with your product?
A: You should use API functions in that case
function dtreet_ext_expandItem (itemID, expand)
function dtreet_ext_setPressedItem (menuInd, itemID)

Q: Does you tree menu javascript support right-to-left layout?
That is to say it opens the branches/submenus from the right to left.
A: Yes it is possible to create a menu for right-to-left languages with Javascript/DHTML Tree in the same way as in standard htmlcode.
Please, set <HTML dir="rtl">. You should set the following parameters:
var titemAlign="right";
var ticonAlign="right";
var texpandBtnAlign="right";
JavaScript Tree Menu support right-to-left languages.
In JavaScript Tree Menu you can set the following parameter:
var dmRTL = 1;
Set this parameter to 1 if you're using right-to-left direction of html page <HTML dir=rtl>.
Q: Drop down menus I have created with your product DHTML Tuner don't look too good in FireFox... is there something I can do different or do you have a newer/better solution that would work for both IE and FireFox?
A: And what exact problems do you have in Firefox? Actually JavaScript Tree Menu works fine inFirefox. But notice that filters and transitional effect are supported by IE5.5.5+ only.
